PatinaPrice

PatinaPrice is a web + mobile app that helps buyers and small dealers sanity-check pricing for pre-owned and vintage jewelry using real-world comps, not wishful listings. Users upload photos, enter basic details (metal, stones, weight if known), and the app returns a price band with confidence levels, plus comparable sold items pulled from marketplaces and auction archives. It flags common pricing traps (overstated era, vague hallmarks, inflated replacement values) and suggests what extra evidence would tighten the estimate (scale photo, hallmark close-up, lab report). This is a combination traditional + AI app: AI handles image-assisted attribute extraction and similarity matching, while the core product is a clean comps workflow and transparent methodology. It’s not an authentication guarantee; it’s a practical “don’t overpay” tool with receipts and links.
